The Argentine Football Association (AFA) condemned the incident and vowed to work with authorities to locate the perpetrators.

"The Argentine Football Association joins with the family of Emanuel Balbo in this difficult and painful moment and strongly condemns the criminal action that occurred in the game between Belgrano and Talleres de Cordoba," it said in a statement.

"This house rejects all these actions, which are those of criminals who deal so much damage to society as a whole and particularly to the footballing family.

"We will offer all possible collaboration with the security services to determine those responsible for this inconceivable aggression, articulating the necessary measures to ensure that incidents such as this do not ever happen again in any Argentine football stadium."

The match between the local rivals finished 1-1, leaving Belgrano second-from-bottom of Argentina's top tier.
